　　Pisco, a potent brandy distilled from grapes, is made in Peru and Chile, and each country claims the pisco sour—recognizable by its distinctive foamy head (from egg white) and tart lime flavor—as its own. A swirl of fresh pineapple juice boosts the tropical vibe.

　　

Ingredients

Makes 8 drinks

　　3 cups (1-inch) pineapple chunks (from 1/2 pineapple)

　　1 1/2 cups pisco (preferably Peruvian; 12 ounces)

　　1/2 cup fresh lime juice (preferably Key lime)

　　4 large egg whites

　　1/3 cup superfine granulated sugar

　　8 drops Angostura bitters

　　

Step 1

Purée pineapple in a blender until very smooth. Force through a fine-mesh sieve into a bowl, pressing hard on and then discarding solids. (You should have about 1 3/4 cups juice.)

　　

Step 2

Return pineapple juice to blender and add remaining ingredients, except bitters, then pulse until smooth and foamy.

　　

Step 3

Pour over ice in glasses. Add a drop of bitters to center of each drink.
